Description

Apparatus of manufacturing eco felt insulator for Heater jacket}

The present invention relates to an apparatus for manufacturing a non-woven insulation material, and more particularly, to an apparatus for manufacturing a non-woven insulation material used in a heater jacket having an insulation material using a nonwoven fabric.

In processes such as semiconductors, LCDs, and equipment manufacturing, piping temperature is maintained at a specific temperature to prevent fluids such as liquids or gases from solidifying and depositing on the inner surface of the transport path. To this end, the outer surface of the fluid transport path, such as piping, tubes, and valves, is wrapped with a heater jacket in which the heating wire is embedded, and the heating pipe is heated to a specific temperature with the heating wire. In the case of the heater jacket, the heating wire is buried in order to prevent heat generated by supplying electricity to the heating wire from being discharged to the outside atmosphere and thereby reduce power consumption, while preventing the operator from being burned even when the heater jacket is in contact with the heater jacket. Wrap the heating pad with a thermal insulation material.

Heater jackets are variously presented in Korean Patent Registration No. 10-1562238. Meanwhile, the heater jacket insulation material is a material having flame retardancy, heat retention, and heat insulation, and a lot of glass fibers have been conventionally used. However, glass fiber causes fatal diseases such as respiratory diseases and skin diseases caused by dust, and acts as a pollutant in semiconductor processes. In addition, the glass fiber has an environmental problem in the process of disposal, and because it is a fiber material, it is difficult to precisely process the piping, thereby increasing the heat retention, but the temperature uniformity of the entire heater jacket is also poor.

Synthetic resins such as polytetrafluoroethylene (PTFE) to replace them are relatively expensive, and the manufacturing cost of the heater jacket is high. Accordingly, there is a need for a new insulating material having low flame retardancy, heat retention, and heat insulation required by the heater jacket while being inexpensive. In addition, insulating materials using synthetic resins are hardly permanently decomposed in the natural environment, and affect the skin and respiratory tract in the manufacturing process, thereby harming health.

The problem to be solved by the present invention is to provide an eco-friendly non-woven insulation manufacturing apparatus for an environmentally friendly and harmless heater jacket that is biodegradable, having low cost and having flame retardancy, heat retention, and heat insulation properties required by a heater jacket.

In the apparatus for manufacturing an eco-friendly non-woven insulating material for a heater jacket for solving the problem of the present invention, a dissociation device in which fibers in the form of fibers and a dispersion medium are released and dissociated, and kneading to form a suspension by kneading the dissociated bundle fibers and dispersion medium And a web former that separates the dispersion medium from the suspension and the suspension to form a fiber aggregate. In addition, a pre-dryer for preliminarily drying the fiber aggregate that has passed through the web forming machine to form a preliminary nonwoven fabric and a heater in which the preliminary nonwoven fabric is contacted to form a nonwoven fabric. At this time, the non-woven fabric constitutes the heat insulating material of the heater jacket including the heating element and the heat insulating material.

In the device of the present invention, binder fibers may be further added to the dissociator. The binder fiber may be added in an amount of 20 to 30% by weight based on the weight of the fiber. The binder fiber is a polyvinyl alcohol (PVA; PolyVinylAlcohol, polyvinyl butyral (PVB; PolyVinylButyral), ethyl butyl acetate (EVA; EthylButylAcetate), any one fiber selected from thermoplastic polyurethane (polyurethane) or a mixture of the fibers) Can.

In a preferred apparatus of the present invention, the web former comprises a dispersion medium separator separating the dispersion medium and a screen mesh passing through the dispersion medium and discharging it to the outside of the web former. The web forming machine further includes an inhaler for forcibly separating the dispersion medium. The heater jacket is a cylindrical hollow tube formed by sequentially stacking an outer shell, a heat insulating material, a heating element shell, a heating element, and a heating element inner shell, and the outer shell is exposed to the outside of the heater jacket and transports a fluid such as the liquid or gas.

According to the apparatus for manufacturing an eco-friendly non-woven insulation material for a heater jacket of the present invention, by using a non-woven fabric of a monocotyledonous plant, it has low flame retardancy, heat retention and heat insulation properties required by the heater jacket, is biodegradable, eco-friendly and harmless to the human body Do.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art. On the other hand, terms indicating the location, such as top, bottom, front, etc., are only related to those shown in the drawings.

An embodiment of the present invention proposes an apparatus for manufacturing a non-woven insulating material that is eco-friendly and has no flame retardancy, heat retention, and heat insulation required by a heater jacket while being cheap, and is biodegradable by using a non-woven fabric of a monocotyledonous willow. To this end, the structure of the heater jacket using a non-woven fabric will be described in detail, and a method of manufacturing the heater jacket will be described in detail. In the heater jacket of the present invention, an electric heating wire is buried, and the outer surface of a fluid transport path such as a pipe, a tube, and a valve is wrapped, and the electric heating wire serves to heat the pipe and the like to a specific temperature.

1 is a perspective view showing a heater jacket using a nonwoven fabric according to an embodiment of the present invention. However, the drawings are not intended to be in an exact sense, and may not be shown in the drawings for the convenience of description. For example, a process of adding a preservative to prevent spoilage may be added in the process of storing the non-woven fabric.

According to FIG. 1, the cut-out heater jacket according to the embodiment of the present invention includes a socket 10 and a heating tube 20 connected via an insulation wire 11 as a cylindrical hollow tube surrounding a pipe. Inside the hollow tube, the socket 10 is connected to a power source, and supplies electric power to the heating element 24 inside the heating tube 20 via an insulation wire 11. The insulation wire 11 is wrapped with a tube made of a heat-resistant and fire-resistant material. The structure of the socket 10, the insulating wire 11 and the heating tube 20 can be variously modified within the scope of the present invention. Here, only one example of a heater jacket is presented.

The heating tube 20 is formed by sequentially stacking an outer shell 21, an insulator 22 by a non-woven fabric, a heating element shell 23, a heating element 24, and a heating element inner shell 25. The outer cover 21 is exposed to the outside of the heating tube 20, and a silicone composition having heat resistance and flexibility, a Teflon composition, a polyvinyl chloride composition, or the like can be used. Both sides of the heating element 24 are covered with a heating element shell 23 and a heating element inner shell 25. The heating element outer cover and the inner cover 23, 25 are made of a polymer having heat resistance, and a flame retardant, ceramic powder, etc. are mixed to improve the heat resistance. The outer shell 21, the heating element shell 23, and the heating element inner shell 25 can be applied to any known material, and thus detailed description thereof will be omitted.

Insulating material 22 according to an embodiment of the present invention is to prevent the heat of the heating tube 20 is not lost to the outside, employs a non-woven fabric. Wealth is biodegradable, which is easily decomposed in the natural environment, and is not harmful to human health. Genus Typha L. is a perennial plant belonging to the genus Typhaceae and has 9 to 18 species distributed worldwide. It is known that there are three types of wild species in Korea: Typha orientalis, Typha angustata and Typha latifolia. Big and small parts are easily divided by the width of the leaves, but these two types have surgery and pistils, whereas the baby parts have narrow leaves and the upper part and the surgery are separated by 4 to 6 cm.

In Korea, the most commonly found across the country are baby girls. In America, broad leaves are called broad-leaved cattai or common cattail, and narrow leaves are called narrow-leaved cattail. In the latter case, the surgical and pistil parts are separated, as are the baboons native to Korea, but the morphological characteristics are found to be somewhat different. In winter, the ground is dry, and the ground part is hibernating with a subterranean mirror. The pollen of the buds is called phoenix, and it is used a lot in Chinese medicine materials, and young shoots, stems, and roots are also used for food.

Non-woven fabrics are fibers that are not spun, weaved or braided, but are combined with fibers of a thin layered fiber aggregate by chemical or mechanical methods. The non-woven fabric is excellent in heat insulating properties while satisfying the properties of low density and light weight required by the heat insulating material 22 of the heating tube 20. In addition, since non-woven fabrics are commonly found all over the country in Korea, the production cost is lower than that of conventional plastic insulation.

Figure 2 is a flow chart showing a process for manufacturing a non-woven fabric to be applied to the heater jacket according to an embodiment of the present invention. FIG. 3 is photographs corresponding to the main process of FIG. 2. In this case, the heater jacket will be referred to FIG. 1.

Referring to Figures 2 and 3, the manufacturing of the non-woven fabric is first, dissociated by putting the fiber-type bundle fibers and dispersion medium into the dissociator 100 at a predetermined ratio. The process of forming the fibrous form of the pulp utilizes known methods such as cutting and grinding. The weight of the puddle fiber of the present invention is based on the technical idea for manufacturing a puddle nonwoven fabric applied to a heater jacket. Accordingly, the weight of the fiber will not be obtained through simple repetitive experiments without considering the technical idea. The puddle fiber and dispersion medium input to the dissociator 100 are moved to the kneader 102 to make a suspension by the puddle fiber and dispersion medium. The kneader 102 may uniformly disperse the swelled fibers in the dispersion medium by rotation, vibration, or the like.

Meanwhile, binder fibers may be introduced into the dissociator 100. The binder fiber is to increase the bonding strength of the nonwoven fabric, any one selected from polyvinyl alcohol (PVA; PolyVinylAlcohol, polyvinyl butyral), ethyl butyl acetate (EVA; EthylButylAcetate), thermoplastic polyurethane (polyurethane) The fiber or the fibers may be mixed, the binder fiber may be mixed by 20 to 30 weight with respect to the weight of the bundle fiber The weight of the binder fiber takes into account the technical idea of increasing the bonding force of the non-woven fabric However, it cannot be obtained through a simple repetition experiment For convenience of explanation, it is assumed that the binder fibers are not mixed.

The suspension of the pulp fibers and dispersion medium is introduced into the web former 104 to form a fiber aggregate. The web former 104 is composed of a dispersion medium separator 105 for separating the dispersion medium, a suction 106 and a screen mesh 107. The dispersion medium separator 105 naturally separates the dispersion medium from the suspension, and the inhaler 106 forces the dispersion medium to be separated. The screen mesh 107 has a plurality of mesh holes, so that the dispersion medium is sufficiently passed and discharged to the outside of the web forming machine 104. The screen mesh 107 is moved by the rotation of the roller 108. The dispersion medium is extracted by the dispersion medium separator 105 and the inhaler 106 and removed through the screen mesh 107, so that the suspension fibers are aggregated with each other and converted into a fiber aggregate (web).

The fiber aggregate (web) from which the dispersion medium is extracted is moved to a pre-dryer (110) to remove the remaining dispersion medium. The pre-dryer 110 is preferably hot air dried, and when pre-dried, the fiber aggregate (web) is partially solidified. This partially solidified fiber aggregate (web) is called a preliminary non-woven fabric. The pre-drying non-woven fabric having passed through the pre-dryer 110 is converted into a wadding non-woven fabric (CF) according to an embodiment of the present invention while being dried by contacting at least one heater 112. The temperature of the heater 112 is preferably about 100 ℃ ~ 130 ℃. Preliminary parts introduced into the heater 112 Since the nonwoven fabric is partially solidified, the rigidity for injecting into the heater 112 is sufficient. Buddle non-woven fabric (CF) that has passed through the heater 112 is wound up by a winding machine 114.

Figure 4 is a photograph showing the fiber assembly (web) before the pre-dryer 110 according to an embodiment of the present invention and a non-woven fabric passed through the heater 112. As shown, the softer nonwoven fabric is swollen compared to the fiber aggregate (web), thereby increasing the pores inside. When the inside pores are increased, the heat insulation characteristics of the heating tube 20 can be improved while the density and light weight required by the heat insulating material 22 are low.

As mentioned above, although the present invention has been described in detail with reference to preferred embodiments, the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is possible.
